Rename notification property `enable_stream_sounds` to
`enable_stream_audible_notifications` to match with other
notification property patterns.
Fixes part of #12304
This adds a setting to control Zulip's default behavior of sorting to
bottom and graying out inactive streams. The previous logic is still
the default "automatic", but this gives users more control. See the
models.py comment for details.
Fixes#11524.
This renames Subscription.in_home_view field to is_muted, for greater
clarity as to what it does just from seeing the setting name, without
having to look it up.
Also disabled an obsolete test_migrations test.
Fixes#10042.
This commit migrates the Subscription's notification fields from a
BooleanField to a NullBooleanField where a value of None means to
inherit the value from user's profile.
Also includes a migrations to set the corresponding settings to None
if they match the user profile's values. This migration helps us in
getting rid of the weird "Apply to all" widget that we offered on
subscription settings page.
The mobile apps can't handle None appearing as the stream-level
notification settings, so for backwards-compatibility we arrange to
only send True/False to the mobile apps by applying those defaults
server-side. We introduce a notification_settings_null value within a
client_capabilities structure that newer versions of the mobile apps
can use to request the new model.
This mobile compatibility code is pretty effectively tested by the
existing test_events tests for the subscriptions subsystem.
This commit replaces the `create_stream_by_admins_only` setting with a
new `create_stream_policy` setting, which mirroring the structure of
the existing `invite_to_stream_policy`.
This is important preparation for migrating the waiting period feature
to be its own independent setting.
Fixes#12236.
This is useful when syncing avatars from an integrated LDAP/active
directory.
The upload avatar and delete avatar buttons are hidden if avatar
changes are disabled and the user is a non-admin.
If the user has a gravatar set, then the user will not be able to
upload an image as their avatar if avatar changes are disabled.
Part of #12132.
This commit creates a new organization setting that determines whether
a user can invite other users to streams. Previously this was linked
to the waiting period threshold, but this was both not documented and
overly limiting.
With significant tweaks by tabbott to change the database model to not
involve two threshhold fields, edit the tests, etc.
This requires follow-up work to make the create stream policy setting
work how this code implies it should.
Fixes#12042.
Allow realms to specify the day of the week when the digest should be sent out.
When enqueue-ing digests, pick only the realms that chose the current weekday as
the day to send out digests.
Follow up on 92dc363. This modifies the ScheduledEmail model
and send_future_email to properly support multiple recipients.
Tweaked by tabbott to add some useful explanatory comments and fix
issues with the migration.
This field is primarily intended to support avoiding displaying the
"more topics" feature in new organizations and streams, where we might
know that all messages in the stream are already available in the
browser.
Based on original work by Roman Godov, and significantly modified by
tabbott.
The second migration involved here could be expensive on Zulip Cloud,
but is unlikely to be an issue on other servers.
In commit de65a04 we can see that if the need ever arises to modify
how stream descriptions are rendered, we would need to make changes
at 5 different call points which can be quite cumbersome. So this
functionality has been extracted to a new method called
'render_stream_descriptions'.
We want to use the baseline features of bugdown, but not fancy things
like inline URL previews, since the whole structure of stream
descriptions is to have a single-line thing supporting some
formatting.
The migration part of this change fixes a bug encountered by some
organizations upgrading from older versions of Zulip.
This commit does the following three things:
1. Update stream model to accomodate rendered description.
2. Render and save the stream rendered description on update.
3. Render and save stream descriptions on creation.
Further, the stream's rendered description is also sent whenever the
stream's description is being sent.
This is preparatory work for eliminating the use of the
non-authoritative marked.js markdown parser for stream descriptions.
This adds a setting under "Notification" section of
"Organization settings" tab, which enables Organization administrator to
control whether the missed message emails include the message content or
not.
Fixes: #11123.
Since we have already added the `invite_as` field to models, we can now
replace usage of `invite_as_admin` properly with its equivalent `invite_as
== PreregistrationUser.INVITE_AS['REALM_ADMIN']`.
Hence, also removed now redundant `invite_as`.
This adds a model field `invited_as` to PreregistrationUser model class
which will replace `invited_as_admin` in future. Intentions behind adding
this are that we can specify "types" of users for an invited person other
than admin or regular that is, guest user or maybe many others in the
future.
This adds a new realm_logo field, which is a horizontal-format logo to
be displayed in the top-left corner of the webapp, and any other
places where we might want a wide-format branding of the organization.
Tweaked significantly by tabbott to rebase, fix styling, etc.
Fixing the styling of this feature's loading indicator caused me to
notice the loading indicator for the realm_icon feature was also ugly,
so I fixed that too.
Fixes#7995.
Also, add a new notification sound, "ding". It comes from
https://freesound.org, where the original Zulip notification sound comes
from as well. In the future, new sounds can be added by adding audio
files to the `static/audio/notification_sounds` directory.
Tweaked significantly by tabbott:
* Avoided removing static/audio/zulip.ogg, because that file is
checked for by old versions of the desktop app.
* Added a views check for the sound being valid + tests.
* Added additional tests.
* Restructured the test_events test to be cleaner.
* Removed check_bool_or_string.
* Increased max length of notification_sound.
* Provide available_notification_sounds in events data set if global
notifications settings are requested.
Fixes#8051.
This is preparatory work for settings controlling who can see user
emails; it includes the API-level support for editing it, but no code
to actually enforce the policy.
This is the first step of letting users use Zulip markdown in their
SHORT_TEXT and LONG_TEXT custom profile fields, so that they can
include emphasis, links, etc.
This doesn't include any frontend logic yet, however.
This reverts commit 3645bb9225.
This change was incorrect, because the `is_zephyr_mirror_realm`
property on Realm is a property and thus isn't available in the
migration codebase.
Since this migration is only run for very old servers, this should
have no impact.
Previously, Zulip did not correctly handle the case of a mobile device
being registered with a push device token being registered for
multiple accounts on the same server (which is a common case on
zulipchat.com). This was because our database `unique` and
`unique_together` indexes incorrectly enforced the token being unique
on a given server, rather than unique for a given user_id.
We fix this gap, and at the same time remove unnecessary (and
incorrectly racey) logic deleting and recreating the tokens in the
appropriate tables.
There's still an open mobile app bug causing repeated re-registrations
in a loop, but this should fix the fact that the relevant mobile bug
causes the server to 500.
Follow-up work that may be of value includes:
* Removing `ios_app_id`, which may not have much purpose.
* Renaming `last_updated` to `data_created`, since that's what it is now.
But none of those are critical to solving the actual bug here.
Fixes#8841.
This fixes an inconsistent test failure with test_users.py (that
depended on the ordering between this migration and the creation of
test database users like hamlet).
This is largely inspired by requests from people not liking the
Google's new emojiset. A lot of people were requesting to revert
back to old blobs emojiset so we are re-enabling this feature
after making relevant infrastructure changes for supporting google's
old blob emojiset and re-adding support for twitter emojiset.
Fixes: #10158.
This adds a feature in the "Notification" section of "Settings" tab,
which lets user enable or disable login emails notification.
Tweaked by tabbott to simplify the test.
Fixes: #5795, progress towards #5854.
Due to copyright issues with potentially displaying Apple emojisets on
non-apple devices, as well as iamcal dropping support for the emojione
emojiset (see https://github.com/iamcal/emoji-data/pull/142), we are
dropping (perhaps temporarily) support for allowing users to switch
emojisets in Zulip.
This commit just hides the feature from the user but leaves most of
the infrastructure in place so that in the future if we decide to
re-enable the support we will not need to redo the infrastructure work
(some JS-side code is deleted, mostly because we'll want to re-add the
feature using the do_settings_change infrastructure anyway).
The most likely emoji set to add is the legacy "blobs" Google emoji
set, since it seems popular with some users.
Tweaked by tabbott to remove some additional JS code and update the
changelog.
This flag is used to track which user/message pairs correspond to an
active mobile push notification, that should potentially be cleared
when the user reads the message.
This flag should never appear on a message that is also marked as
read; eventually we may want a cron job to check for that condition.
We include a partial index on UserMessage for this flag.
This renames Realm.show_digest_email field to
digest_emails_enabled, for greater clarity as to what it does
just from seeing the setting name, without having to look it up.
Fixes part of #10042.
This renames Realm.restricted_to_domain field to
emails_restricted_to_domains, for greater clarity as to what it does
just from seeing the setting name, without having to look it up.
Fixes part of #10042.
The is_private flag is intended to be set if recipient type is
'private'(1) or 'huddle'(3), otherwise i.e if it is 'stream'(2), it
should be unset.
This commit adds a database index for the is_private flag (which we'll
need to use it). That index is used to reset the flag if it was
already set. The already set flags were due to a previous removal of
is_me_message flag for which the values were not cleared out.
For now, the is_private flag is always 0 since the really hard part of
this migration is clearing the unspecified previous state; future
commits will fully implement it actually doing something.
History: Migration rewritten significantly by tabbott to ensure it
runs in only 3 minutes on chat.zulip.org. A key detail in making that
work was to ensure that we use the new index for the queries to find
rows to update (which currently requires the `order_by` and `limit`
clauses).
This deletes the unused Subscription.notifications field and removes
it from some testing and analytics code (which should not have been
using it in the first place).
Fixes#10042.
This commit creates a new field called delivery_email. For now, it is
exactly the same as email upon user profile creation and should stay
that way even when email is changed, and is used only for sending
outgoing email from Zulip.
The purpose of this field is to support an upcoming option where the
existing `email` field in Zulip becomes effectively the user's
"display email" address, as part of making it possible for users
actual email addresses (that can receive email, stored in the
delivery_email field) to not be available to other non-administrator
users in the organization.
Because the `email` field is used in numerous places in display code,
in the API, and in database queries, the shortest path to implementing
this "private email" feature is to keep "email" as-is in those parts
of the codebase, and just set the existing "email" ("display email")
model field to be something generated like
"username@zulip.example.com" for display purposes.
Eventually, we'll want to do further refactoring, either in the form
of having both `display_email` and `delivery_email` as fields, or
renaming "email" to "username".
The main remaining todo for correctly populating
RealmAuditLog.requires_billing_update is supporting the de-seating (and
corresponding re-seating) that happens after being offline for two weeks.
We don't want to keep around a declaration of
PRIVATE_STREAM_HISTORY_FOR_SUBSCRIBERS forever, so we should just move
this to a getattr; if the user has set it on their server, we'll use
the value; otherwise, we just use False.
This should make it easier for us to iterate on a less-dense Zulip.
We create two classes on body, less_dense_mode and more_dense_mode, so
that it's easy as we refactor to separate the two concepts from things
like colors that are independent.
The "Short/Long Text" option for custom profile fields wasn't properly
capitalized (i.e. "Text" should have been all lowercase), and also
wasn't properly tagged for translation.
For the sake of consistency, the change to proper capitalization has
also been applied to the models and any tests involving this feature.
Due to a bug in Django, it complained about the models having changed
and thus not being consistent with the migrations. That isn't actually
true (since the database stores the numeric values for each key), but
the migrations have been modified to avoid this error. This does not
affect the migrations' behaviour in any way.
This commit adds a new field history_public_to_subscribers to the
Stream model, which serves a similar function to the old
settings.PRIVATE_STREAM_HISTORY_FOR_SUBSCRIBERS; we still use that
setting as the default value for new streams to avoid breaking
backwards-compatibility for those users before we are ready with an
actual UI for users to choose directly.
This also comes with a migration to set the value of the new field for
existing streams with an algorithm matching that used at runtime.
With significant changes by Tim Abbott.
This is an initial part of our efforts on #9232.
Add realm setting to set time limit for message deleitng.
Set default value of message_content_delete_limit_seconds
to 600 seconds(10 min).
Thanks to Shubham Dhama for rebasing and reworking this. Some final
edits also done by Tim Abbott.
Fixes#7344.
This fixes a bug where the endpoint for editing bot users would allow
an organization administrator to edit the full name of a bot user.
A combination of this an another recently fixed bug made it possible
for this process to set a `bot_owner` for a non-bot user; so we also
include a migration to fix that for any users that might have had our
model invariants corrupted in that way.
This was causing a rather confusing test flake in
test_stream_error_pm_to_bot_owner. What was happening was that if
this test (which used that code path) ran within 5 minutes of the
populate_db run, it would fail.
This commit migrates realm emoji to be addressed by their `id` rather
than their name. This fixes a long standing issue which was causing
an error on uploading an emoji with same name as a deactivated realm
emoji.
Fixes: #6977.
The original implementation of this migration had a highly unfortunate
bug that would result in it deleting all reactions to realm emoji on
the server; we missed this in review, so essentially all historical
realm emoji reactions on chat.zulip.org were lost :(.
We both correct the problem, and also add logging of the deleted rows
that would help should anything be deleted erroneously.
This makes this value much easier for a server admin to change than it
was when embedded directly in the code. (Note this entire mechanism
already only applies on a server open for anyone to create a realm.)
Doing this also means getting the default out of the database.
Instead, we make the column nullable, and when it's NULL in the
database, treat that as whatever the current default is. This better
matches anyway the likely model where there are a few realms with
specially-set values, and everything else should be treated uniformly.
The migration contains a `RenameField` step, which sounds scary
operationally -- but it really does mean just the *field*, in
the model within the Python code. The underlying column's name
doesn't change.
If an emoji that was deleted was the only realm emoji, or more
generally if all realm emoji were deleted, then we would just leave
the reaction unchanged, with an `emoji_code` that is now corrupt.
Instead, treat this case the same as if only this emoji was deleted
while others remain.
Till now, we had been storing realm emoji's name in emoji code field
in reactions' model. This commit migrates it to store realm emoji's id.
It is a part of effort to migrate realm emojis to be referenced by their
id and not by name.
Add `translate_emoticons` to `prop_types` and `expected_keys`.
Furthermore, create a emoji-translating Markdown inline pattern.
Also use a JavaScript version of `translate_emoticons` and then use
this function during Markdown previews and as a preprocessor. This
is only needed for previews, because usually emoticon translation
happens on the backend after sending.
Add tests for emoticon translation, a settings UI, and a /help/ page
as well.
Tweaked by tabbott to fix various test failurse as well as how this
handles whitespace, requiring emoticons to not have adjacent
characters.
Fixes#1768.
Creating the very first organization administrator user and
subscribing them to streams before any messages were sent resulted in
RealmAuditLog entries being created with a `event_last_message_id` of
None, because that's the maximum ID in the empty set.
We correct this by fixing the incorrectly created RealmAuditLog
entries, both for new servers and also fixing old broken entries on
existing servers.
This fixes an issue where if a user setup a Zulip server with just the
organization administrator, and then forgot about it (so that the
initial user became soft-deactivated), trying to sign in 3 weeks later
would throw an exception.
This fixes the issue reported here:
https://chat.zulip.org/#narrow/stream/9-issues/subject/500.20error.20on.20login/near/511981
Users having only account in one realm will not be distracted by realm
name in subject lines of every email. Users who have multiple
accounts in realms can turn this setting on and receive a
corresponding realm name in email's subject.
Tweaked by tabbott to rebase and address a few small issues.
Fixes#5489.
This is easy to do, and prevents this feature from getting a server
admin stuck in potentially a pretty uncomfortable way -- unable to
roll back a deploy.
This reverts commit acebd3a5e, as well as a subsequent fixup commit
0975bebac "quick fix: Fix migrations to be linear."
These changes need more work and thought before they're ready to
deploy on any large established Zulip server, such as zulipchat.com.
See discussion on #6534.
In place of the removed migration, leave behind a placeholder so
`manage.py migrate` doesn't get confused on installs where it was
already applied.
This commit adds a setting to limit creation of generic bots
to admins for realms that want that restriction. (Generic
bots, apart from being considered spammy on some realms,
have less locked down permissions than webhook bots).
Fixes#7066.
We no longer have a special UI setting and model
field ("emoji_alt_code") for saying users want text-only
emojis. We now instead make "text" be a fifth choice
for "emojiset".
Fixes#7406
Commit d4ee3023 and its parent have the history behind this code.
Since d4ee3023^, all new PreregistrationUser objects, except those for
realm creation, have a non-None `realm`. Since d4ee3023, any legacy
PreregistrationUsers, with a `realm` of None despite not being for
realm creation, are treated as expired. Now, we ignore them
completely, and remove any that exist from the database.
The user-visible effect is to change the error message for
registration (or invitation) links created before d4ee3023^ to be
"link does not exist", rather than "link expired".
This change will at most affect users upgrading straight from 1.7 or
earlier to 1.8 (rather than from 1.7.1), but I think that's not much
of a concern (such installations are probably long-running
installations, without many live registration or invitation links).
[greg: tweaked commit message]
[Modified by greg to (1) keep `USERNAME_FIELD = 'email'`,
(2) silence the corresponding system check, and (3) ban
reusing a system bot's email address, just like we do in
realm creation.]
Storage limititations are only set on the value of
a config entry, since this is the only user-accessible
part of the schema. Keys are statically set by each
embedded bot.
This restyles and rewords some of the emoji style section to look
better and fit it more with the current style guide.
Tweaked by tabbott to modify the historical migration rather than
adding a new one. This is OK because the emojiset choices text change
doesn't touch the database; it's just a Django Python code thing.
Also removed translation tags, since we don't need them for a set of
brand names.
This adds the data model and bugdown support for the new UserGroup
mention feature.
Before it'll be fully operational, we'll still need:
* A backend API for making these.
* A UI for interacting with that API.
* Typeahead on the frontend.
* CSS to make them look pretty and see who's in them.
Tweaked by tabbott to have the field before the invitation is
completed be called invite_as_admins, not invited_as_admins, for
readability.
Fixes#6834.
Add this field to the Stream model will prevent us from having
to look at realm data for several types of stream operations, which
can be prone to either doing extra database lookups or making
our cached data bloated.
Going forward, we'll set stream.is_zephyr to True whenever the
realm's string id is "zephyr".
We need a migration to clear the tutorial_status for existing users,
so that we don't show hotspots to anyone who signed up for Zulip in
the month or so since we deleted the old tutorial.
We should have done this a long time ago, but better late than never.
Basically, this migration would crash in the event that there were any
attachments with particularly long names. The fix is the next
migration, 0042; we just inline it here to avoid that crash.
This commit completely switches us over to using a
dedicated model called MutedTopic to track which topics
a user has muted.
This includes the necessary migrations to create the
table and populate it from legacy data in UserProfile.
A subsequent commit will actually remove the old field
in UserProfile.
This is the first part of a larger migration to convert Zulip's
reactions storage to something based on the codepoint, not the emoji
name that the user typed in, so that we don't need to worry about
changes in the names we're using breaking the emoji storage.
This fixes a performance issue that caused this migration to run for a
really long time.
It still takes about 1 minute to run with the 75K Subscription objects
we have on chat.zulip.org, but that's within the realm of acceptable.
ScheduledJob was written for much more generality than it ended up being
used for. Currently it is used by send_future_email, and nothing
else. Tailoring the model to emails in particular will make it easier to do
things like selectively clear emails when people unsubscribe from particular
email types, or seamlessly handle using the same email on multiple realms.
This new setting controls whether or not users are allowed to see the
edit history in a Zulip organization. It controls access through 2
key mechanisms:
* For long-ago edited messages, get_messages removes the edit history
content from messages it sends to clients.
* For newly edited messages, clients are responsible for checking the
setting and not saving the edit history data. Since the webapp was
the only client displaying it before this change, this just required
some changes in message_events.js.
Significantly modified by tabbott to fix some logic bugs and add a
test.
In this commit we are adding two new fields to the UserProfile
table. These fields are the:
long_term_idle: For storing a bool value representing status of user
being online in long time where 'long' will have a specific
definition.
last_active_message_id: For storing the message id which was last
updated into the UserMessage table for a particular user.
This system hasn't been in active use for several years, and had some
problems with it's design. So it makes sense to just remove it to declutter
the codebase.
Fixes#5655.
This will allow for customized senders for emails, e.g. 'Zulip Digest' for
digest emails and 'Zulip Missed Messages' for missed message emails.
Also:
* Converts the sender name to always be "Zulip", if the from_email used to
be settings.NOREPLY_EMAIL_ADDRESS or settings.ZULIP_ADMINISTRATOR.
* Changes the default value of settings.NOREPLY_EMAIL_ADDRESS in the
prod_setting_template to no longer have a display name. The only use of
that display name was in the email pathway.
Once we implement org_type-specific features, it'll be easy to change a
corporate realm to a community realm, but hard to go the other way. The main
difference (the main thing that makes migrating from a community realm to a
corporate realm hard) is that you'd have to make everyone sign another terms
of service.
Instead of deleting the emojis we will just mark them as `deactivated`.
This will prevent their further use but at the same time they will be
displayed properly in the reactions and messages in which they are used.
This field will be used as a flag to indicate whether the realm emoji
has been deleted or not.
Includes a database migration.
This index is basically free, since it only consumes space for
messages that mention the user, but results in a massive performance
improvement when querying messages that mention a user.
This index is essentially free, since it only consumes resources for
starred messages, and massively improves the performance of the
"starred messages" narrow.
Since realm emoji are now required to be lowercase,
an appropriate migration was added to retroactively
fix any emoji that might have contained uppercase
letters.
Also, the validator on the model was changed to
reject uppercase letters.
- Add file_name field to `RealmEmoji` model and migration.
- Add emoji upload supporting to Upload backends.
- Add uploaded file processing to emoji views.
- Use emoji source url as based for display url.
- Change emoji form for image uploading.
- Fix back-end tests.
- Fix front-end tests.
- Add tests for emoji uploading.
Fixes#1134
Useful for the upcoming check_realmauditlog_by_user_query, if nothing else.
But I suspect it will indeed get use; looking for events around or within a
certain time is pretty natural for an audit log.
The main argument against I would say is that this should actually be a
joint index with something else. I'm not sure what that something else
should be, so just optimizing for what I think
check_realmauditlog_by_user_query will need for now.
This commit adds the backend support for a new style of tutorial which
allows for highlighting of multiple areas of the page with hotspots that
disappear when clicked by the user.
This adds an organization description field to the Realm model, as well as
an input field to the organization settings template. Added three tests.
Set the max length of the field to 100 characters.
Fixes#3962.
This makes the outcome if a user didn't have an avatar due to a past
email change reasonable; the user will just be bumped back to
gravatar, fixing their invalid state.
This commit introduces a migration for moving avatars from email based
to user id based storage.
This is in responce to change in behaviour of user_avatar_path to
return path comprising of realm id and a hash based on user id. Also
we fix test_helpers accordingly.
Fixes#3776.
This currently only supports this in emoji reactions, not in actual
emoji in message bodies, but it's a great start for people who want a
text-only view.
Tweaked to update the text by tabbott.
Fixes#3169.
This adds to Zulip support for a user changing their own email
address.
It's backed by a huge amount of work by Steve Howell on making email
changes actually work from a UI perspective.
Fixes#734.
This adds support for only allowing normal users with account age
equal or greater than a "waiting period" threshold to create streams;
this is useful for open organizations that want new members to
understand the community before creating streams.
If create_stream_by_admins_only setting is set to True, only admin users
were able to create streams. Now normal users with account age greater
or equal than waiting period threshold can also create streams.
Account age is defined as number of days passed since the user had
created his account.
Fixes: #2308.
Tweaked by tabbott to clean up the actual can_create_streams logic and
the tests.
This commit adds the following:
1. A reaction model that consists of a user, a message and an emoji that
are unique together (a user cannot react to a particular message more
than once with the same emoji)
2. A reaction event that looks like:
{
'type': 'reaction',
'op': 'add',
'message_id': 3,
'emoji_name': 'doge',
'user': {
'user_id': 1,
'email': 'hamlet@zulip.com',
'full_name': 'King Hamlet'
}
}
3. A new API endpoint, /reactions, that accepts POST requests to add a
reaction to a message
4. A migration to add the new model to the database
5. Tests that check that
(a) Invalid requests cannot be made
(b) The reaction event body contains all the info
(c) The reaction event is sent to the appropriate users
(d) Reacting more than once fails
It is still missing important features like removing emoji and
fetching them alongside messages.
This migration ensures that all historically uploaded files from
before we started tracking files in the Zulip database via the
Attachment model have Attachment objects.
This has been tested by tabbott against a production server to ensure
that it results in all old uploaded files having corresponding
attachment objects.
Merging this change is a key prerequisite for making our adding
attachment access controls in an enforcing fashion.
This makes it possible to configure only certain authentication
methods to be enabled on a per-realm basis.
Note that the authentication_methods_dict function (which checks what
backends are supported on the realm) requires an in function import
due to a circular dependency.
Removes the uniqueness constraint on RealmAlias.domain, and adds a function
can_add_alias that checks for uniqueness conditional on
settings.REALMS_HAVE_SUBDOMAINS.
Previously, we set restrict_to_domain and invite_required differently
depending on whether we were setting up a community or a corporate
realm. Setting restrict_to_domain requires validation on the domain of the
user's email, which is messy in the web realm creation flow, since we
validate the user's email before knowing whether the user intends to set up
a corporate or community realm. The simplest solution is to have the realm
creation flow impose as few restrictions as possible (community defaults),
and then worry about restrict_to_domain etc. after the user is already in.
We set the test suite to explictly use the old defaults, since several of
the tests depend on the old defaults.
This commit adds a database migration.
